Application filed September 20, 1905- SerialNo. 279,215.

"holding and carrying frame capableof yielding. to theforward movement of the block in theevent the said .block does not drop entirely free from the frame when the latter is moved over the compression-chamber.

A further object consists in .providing convenient and effective means for actuating the block-holding frame.

I Referring to the accompanying drawings, Figure 1 represents a side elevation of the rear end of a baling-press embodying my in vention. Fig. 2 is a viewcorresponding with Fig. 1 ,but-with the feedlever in its down position and the block-holding frame in its .forward position. Fig. 3 is a transverse sectional view through the 1press, the view being taken as indicated by. t

Fig; 6 is a detac ed. view showingin inner or rear side elevation the switch, a. front view of which isshown in Fig. 2; and: Fig.7 is a vertical section through same, taken as-indicated by the line 7 7 of Fig. 6.

In the accompanying. drawings, 1 designates the: frame of the press, 2 the balingchamber, :and 3 the compression-chamber.

On the 9 end of the rearwardly-projecting beam 1 of the frame-is pivotally mounted in suitable bearings the 'reciproc'ative feed-lever 4, which is provided onits upper or free end 45 acutatedbymeans of the link 6,- whichdewith the feeder-head 5. The feed-lever 4 is tachably engages the slot 7 in the rearwardlyprojecting bar 8,-secured to. the plunger 9. The short-links 10 control the lower end of the link 6. Theoperation of these links, as well as that of the above-mentioned arts, is clearly set forth in an application fileg by me June 19, 1905, Serial No.' 265,996, b'alingpress.

Pivoted near the-bottom of. the frame 1 on eline 3 3m Fig. 1.. Figs. 4and'5 represent a sideelevation and "plan, respectivel of theblock-holding frame.

the bolts 1 1 are the arms 11- of the block-holding frame. The upper ends of the arms 1 1 "terminate in the laterally-deflected or forwardlybent portions 11 To the free ends of. these deflected portions is pivotally. attached. the frame 12.

This frame 12 is constructed. of the side bars 12, pivoted at13, and to which is secured the sheet-metal plate 12 having the. flange portions 12 The side: bars 12 project a short distance above their pivotal fastenings, and between the :upper projecting which are secured. tothe upper ends of the arms 11,- are interposed the coil compres sion-springs 15, the bolts 16 supporting same and limiting the rocking movement of the frame 12.

The bolt-receiving apertures are made considerably larger than the diameter of the bolts so that a rocking movement of the frame will be permitted. A sheet-metal plate 17 of a width substantially equal .to the length of the I ends thereof and the short extensions 14,

bars 12 is secured to the arms 11 .in a posi tion opposed to the frame 12 and :in connection with said frame for'ms theblock-receiving: chamber 18. A pivotally mounted block-holding frame is thus provided having its forward side pivotally mounted and longitudinally yielding, so that in the event a division-block does 'not drop entirely out of the, frame into the compression-chamber it will not 'resultin' the destruction of said frame, but the forward side by yielding-will .permit the plunger to force the block forward, and no harm will result aside fromv forcing the block in askew'. The dotted lines in' Fig. 4 indicate the position to which said frame may be swung when swung forwardlyjby a disengaged block. Heretofore the forward sideof the block-holdingframe has been con structed rigid, in consequence of which the failure of the block to completely disengage therefrom would result in thedestruction of the frame.

The block-holding frame is actuated by the following described mechanism: An arm '19, provided with. a roller 20, journaled on the free end thereof, is pivotally mounted on the rear end of the baler-frame, and this arm con 'nects with the block-holding frame through the pitman 21. A casting 22 is secured to thefeed-lever 4,: andin this casting is formed the upper and lower cam-grooves 24 and 23, respectively,-which.:unite at their forward ends. The. roller 20 iszarranged, :to; engage said camgrooves, the position of the switch I ver, a double-grooved cam secured to said determining which of the two grooves the roller must follow. The lower cam-groove 23 is made concentric with the pivotal axis of the feed-lever, so that when the switch 25 occupies the position shown in Fig. 1 it will confine the roller on the arm 19 to said lower track and no rocking movement of the arm 19 will result; but when the switch is depressed, as shown in Fig. 2, the roller 20 will be forced into the upper cam-track and the arm 19 will be rocked forwardly. This rocking movement of the arm 19 will also rock the blockholding frame, moving it from the position shown in Fig. 1 to that shown in Fig. 2, thereby permitting a block 26 to drop into the compression-chamber. 7

To operate the switch, a bell-crank lever 27 is journaled in a suitable bearing in the casting 22. The switch-stem 25 is provided with the crank-arm 28, which is connected to the bell-crank by means of the link 29. The coilspring 30, interposed between the casting 22 and the switch-stem 25, operates to hold the switch up in an inoperative position, as shown in Fig. 1. While in practice the switch is co otrolled by the operator grasping the bell-crank 27, a suitable extension may be connected thereto in order that it may be operated from any other part of the machine.

In operation ablock, as 26, is placed within the space 18 of the supporting-frame, the block resting on the upper surface of the baling-chamber, as shown in Fig. 1. When the time for the introduction of same arrives, the bell-crank lever 27 is moved to depress the switch to the position shown in Fig. 2. The next descent of the feed-lever 4 will force the roller-bearing arm 29 forwardly, thus rocking the block-holding frame to a position in which the said block will be permitted to drop into the compression-chamber. On the ascent of the feed-lever all parts will return to their normal position and so remain until the switch 25 is again depressed.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a baling-press, in combination, a block-holding frame, a reciprocating feeding device, a double-grooved cam in connection with said feeding device, a switch in operative relation with the grooves of said cam, and means actuated by the cam-grooves for controlling the movement of the said blockholding frame.

2. In a baling-press, in combination, a block-holding frame, a reciprocating feed-lever having a double-grooved cam in connection therewith, a switch in operative relation with the grooves of said cam, and means actuated by said cam-grooves for controlling the movement of the said block-holding frame.

3. In a baling-press, in combination, a block-holding frame, a reciprocating feed-le feed-lever, a pitman for controlling the movement of the block-holding frame, the forward end of said pitman being arranged to engage either groove of said cam, and a switch for throwing the engaging end. of said pitman into either of the cam-grooves.
